[SOLVED] Custom Combo Box

I can’t find the previous question about the UserPopup. IIRC you were asking about the placement properties.

This is how it works:

• The UserPopup is a UserControl that you can design as any container, with the difference that it is shown using ShowPoup() https://docs.wisej.com/api/wisej.web/containers/wisej.web.userpopup#showpopup-opener-onclose. The ShowPoup() method shows the panel at the specified x,y location *or* links the popup to the opener control specified in the call.
• When ShowPopup(opener) is called, the popup is located on the screen in relation to the opener using the Alignment and PlacementModeX/Y properties. It’s like the combobox dropdown but you can also decided if it pops above, left, right, below and if it aligns to the left, middle, right, etc.
• The system takes care of adjusting the popup location in case it doesn’t fit.
• Once the popup is visible it will move together with the opener in case the form is moved.

The popup closes automatically when the user clicks outside of the popup or a control outside is activated. You can also close it by calling Close(). The Closed even fires when the popup is closed.

It’s a useful control to create complex input widgets, especially if used in conjunction with the tool icons that all input controls accept.

HTH
